In probability theory and statistics, the kth standardized moment of a probability distribution is and#956;k/and#963;k, where and#956;k is the kth momentabout the mean and and#963; is the standard deviation.

In probability theory and statistics, the kth momentabout the mean (or kth central moment) of a real-valued random variable X is the quantity E[(X and#8722; E[X])k], where E is the expectation operator.

In terms of shape, a platykurtic distribution has a smaller "peak" around the mean (that is, a lower probability than a normally distributed variable of values near the mean) and "thin tails" (that is, a lower probability than a normally distributed variable of extreme values).

The most platykurtic distribution of all is the Bernoulli distribution with p = ½ (for example the number of times one obtains "heads" when flipping a coin once), for which the kurtosis is -2.

Mean - The mean is a particularly informative measure of the "central tendency" of the variable if it is reported along with its confidence intervals.

Usually we are interested in statistics (such as the mean) from our sample only to the extent to which they are informative about the population.

The standard error of the mean (first used by Yule, 1897) is the theoretical standard deviation of all sample means of size n drawn from a population and depends on both the population variance (sigma) and the sample size (n) as indicated below:

A moment is an indeterminately short but significant period: I'll be with you in a moment.

Jiffy and flash usually combine with in a; in a jiffy means in a short space of time, while in a flash suggests the almost imperceptible duration of a flash of light: He was on his stool in a jiffy, driving away with his pen (Charles Dickens).

Being in the moment is just another way of saying that we are aware of what is going on in our experience, that we are not just being angry (or whatever) but are aware that we are angry and are aware that we can choose to be otherwise.

Or we may be fantasizing about a future in which we have won the lottery and are living out our lives in some imagined paradise, or daydreaming about being with the perfect partner.

When we are thinking about the past or future while being in the moment, we are conscious that we are reflecting and we're not lost in thought.

In terms of shape, a leptokurtic distribution has a more acute "peak" around the mean (that is, a higher probability than a normally distributed variable of values near the mean) and "fat tails" (that is, a higher probability than a normally distributed variable of extreme values).

In terms of shape, a platykurtic distribution has a smaller "peak" around the mean (that is, a lower probability than a normally distributed variable of values near the mean) and "thin tails" (that is, a lower probability than a normally distributed variable of extreme values).

Mean, median, and mode are all types of averages, although the mean is the most common type of average and usually refers to the _arithmetic mean_ (There are other kinds of means that are more difficult).

But sometimes the arithmetic mean doesn't give you all the information you want, and here is where your first and third questions come in.

Now, mean, median and mode are all good types of averages, and each works best in different types of situations.

Take that in the broadest sense; you may be asked about things that relate to these items, not just these items directly.

There are questions you have to think about, and some that you should be able to answer off the top of your head.

Remember that “to within rounding errors” means the answer could differ by a neighboring digit in the last place offered.

This means you are completely Aware of your body, all sensations of the body, your surroundings, your emotional state, and your mental state, all without doing any "thinking" or "feeling" about it at all.

This means that you are not engaged in the exercise of distinguishing one "part" of Experience from another.

As I contemplated the nature of Moment and moments, I was struck by a nagging familiarity; something about this way of understanding reminded me of something else I would never have connected Moment and moments to before.

The Length of the Lunar Cycle(Site not responding. Last check: 2007-11-06)

Mean Solar Time at the Prime Meridian, running at the same rate as TT but intermittently adjusted to match the observationally determined Earth rotation rate by insertion of leap second(s).

Average lunar conjunction moment, assuming that Moon's orbit is a circle with Earth at its center, and that Earth's orbit is a circle with Sun at its center.

In the present era the median length of the lunar cycle is about 29d 12h 30m, the average (MSM) is slightly more than 29d 12h 44m, the shortest lunations are about 29d 6h 30m, and the longest are about 29d 20h.

The moment is measured from the hinge to the line of action of the force.

Calculating the moment that way involves multiplying two scalars together, after finding the magnitude (scalar length) of the moment arm, and specifying the maximum force as the other scalar quantity.

One way to do that is to specify the moment arm as a vector (distance displacement from the hinge to the point on the force line of action that is closest to the hinge), and specify the other vector as the force (coordinate displacement of the force magnitude and direction).

The comparison of the true meaning of variance, which rests in squaring the deviation scores to obtain their corresponding areas, appearing to be implausible, although it is geometrically correct (as expressed through the words of Professor Keating in Dead Poets Society) and the application of the

The text explains that "the term moment is used in mechanics as a measure of the force of rotation.

To form a z ratio, calculate the difference between a random sample mean and the mean of the population over the standard error of the mean.

Some seem to think that because there is research about namespaces which will be more persistent, that they can be as lax about dangling links as they like as "URNs will fix all that".

Enough people complain all the time about dangling links that I hope the damage is obvious.

Often, this is because they are using tools whose task is seen as to present the best site in the moment, and no one has evaluated what will happen to the links when things change.
